How can the world adapt to COVID-19 in the long term?

As the acute phase of the pandemic passes, COVID-19 will remain with us as an endemic disease—still around, but a manageable threat. What does this mean, and what must we do to stop it from erupting again?

Epidemic

In epidemiology, an epidemic (from Greek epi- upon + demos people) occurs when new cases of a certain disease, in a given human population, and during a given period, substantially exceed what is "expected," based on recent experience (the number of new cases in the population during a specified period of time is called the "incidence rate"). (An epizootic is the analogous circumstance within an animal population.) In recent usages, the disease is not required to be communicable; examples include cancer or heart disease.
